One of the pages is almost certainly wrong, as Intel gives each new generation and architecture a new name.

For example, the decoder page also mentions Coffee Lake, widely believed to be the company's 8th-gen chippery and currently enjoying “pre-release” status, but doesn't say which generation it belongs to.

We probably don't have long to wait to have this straightened out, as The Register understands new Chipzilla CPUs intended for desktops and laptops will debut by the end of this quarter. ®
